Application tiled 23,

To all whom it may concern:

Be it known that I, CELESTINO MARTINEZ, a citizen of the United States, residing at. San Diego, in the county of Duval' and State of lexas,'have invented new and useful Improvements in Cotton-Cleaning Cylinders, of which the following is a specification. y

This invention comprehends the revision of a cotton cleaning machine, inc uding a cylinder having spaced parallel rows of fingers designed and related to engage and move the cotton across the foraminated bottom of the machine without any tendency to tear, twist or roll the same, and also subject the cotton to air currents with a view of cleaning the same.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed. a i

In the drawing forming part of this application like numerals of reference indicate similar parts in the several views. Figure 1 is longitudinal sectional view through the machine.

Figure 2 is a transverse sectional view. The machine forming the subject matter of the present invention includes a box-like casing indicated generally at 10, and which casing includes a curve foraminated bottom 11, through which the foreign matter separated from the cotton is allowed to pass. The cotton is fed into the casing through I an opening 12 in the top thereof, and after i being moved across the bottom 11 in a manner to be hereinafter described,". it passes .from the casing 10 through an outlet shoot 13. The casing 10 is mounted upon suitable supporting legs 14.

" upon the shaft 17.

The opposed endwalls of the casing 10 are provided with openings 15 which receive the cylinder 16, the latter being arranged longitudinally within the casing 10 and mounted in suitable bearings 18, and is provided at one end 'with a pulley 19 over WhlCll 1s adapted to be trained a power belt not shown. The

. cylinder may be made in one piece or in a number of sect10ns gether,

suitably connected tothe opposite end of the cylinder bemg inclosed by heads 20 which are provided with hubs 21 to receive the shaft 17 It well as produci This shaft is journalled 1925. Serial No. 32,419.

of fan blades 22 which rotate within parallel rows tween the various rows of fingers roject' clearly ilustrat in the drawing. It will be noted upon ins ction of Figure 1 that the various rows 0 fingers are equi-distantly spaced apart,both longitudinally and transversely of the cylinder, one row of fin ers indicated at 24 bein slightly longer is an the adjacent row of lingers indicated at 25. While these fingers are substantially coneshaped they do not terminate in pointed ext mities which would obviously tear or olgierwise injure the cotton. The various rows of long and short fingers are alternately arranged about the cylinder as clearly shown in Figure 2 it being understood that the short fingers 2h assist the longer fingers 24 in properly engaging the cotton to move it loosely across the foraminated bottom 11 without any tendency of rolling, twisting, tearing or otherwise in'uring the cotton. It might here be stated t at the cylinder 16 is adapted to be rotated at a much slower speed than the average cylinder now in use, as the best results are obtained with a reduced s eed, which also increasesthe capacity of t e machine. By reason of the construction and arrangement ofthe various rows of fingers, coupledwith the distan at which the cylinder is spaced from the oraminated bottom and the slow speed with which the cylinder is rotated the cotton may be transferred to the belt distributor with the looks as intact as possible, which results in the slight increase in the capacity of the gin, as a better sample. During the rotation of t e cylinder air currents "are forced from the inside thereofthrough the perforations ing across the foraminated bottom with a view of cleaning the cotton, While these air currents also maintain the cylinder'free of cotton which passes over the screen.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I

23, and through the cotton passfrom the cylinder as desire to have it understood that I do not" limitmyself to what is herein shown and described and that such changes may be resort 'ed to when desiredas fall within the of what is claimed.

What-I claim is:

fhmachine of t? character ncllescribed compnsmg'il, casi'n aving'an i et opening in the top thereogia; ouryed, foraminated bot tom, an outlet chute leading'from the casing adjacent the bottom, a cylinder mounted for rotation within the caeing and spaced from the bottom, spaced iongtiudinal rows of fingers projecting from t e cylinder, the fingers of each row being alternate] of relatively difi'erent Ien hs, said cylin er having perforations between the'fingets of each-row,

and being ooncaved between the adjacent rows of said fingers, and fan blades carried purpose specified. r
